      应该是又更近了一步,现在无论是自己基于v4l2写的程序或者是gstreamer获取信息显示的画面都是绿色的v4l2_capture.jpg gstreamer.png
      这是什么情况呢

        @aike 首先,我们这个模组是带有isp的,因此在dts中,isp部分都给bypass掉了。
        其次,你可以先试试我们wiki上的gstreamer例子,看看能不能预览。

          我用gitee上面的gstreamer测试工具测试的时候出现了这些问题62fb8af1-4847-4e61-84f2-64eeecded9d8-image.png
          同时串口会打印这些

            @aike 这个我们在其他的板卡上没有遇到过。你的板子本身没有带gstreamer吗? 或者问问板卡厂家。

              板卡是自带gstreamer的,一直在这里卡住了,会不会是摄像头模组硬件的原因呢

                @aike 可能性很小。你试试用这个脚本抓一下图:

                v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat='NV12' --stream-mmap --stream-count=100 --stream-to=nv12-1920x1080.yuv
                ``

                  我输入了v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat='NV12' --stream-mmap --stream-count=100 --stream-to=nv12-1920x1080.yuv命令之后报这个错误

                    nv12-1920x1080.yuv里面是空的

                      你试一下将驱动中下面这个函数改成如下:

                      static int veyecam2m_enum_frame_sizes(struct v4l2_subdev *sd,
                      				    struct v4l2_subdev_pad_config *cfg,
                      				   struct v4l2_subdev_frame_size_enum *fse)
                      {
                          VEYE_TRACE
                      	if (fse->index >= ARRAY_SIZE(supported_modes))
                      		return -EINVAL;
                      
                      	//if (fse->code != VEYECAM2M_MEDIA_BUS_FMT/*MEDIA_BUS_FMT_UYVY8_2X8*/)
                      	//	return -EINVAL;
                      
                      	fse->min_width  = supported_modes[fse->index].width;
                      	fse->max_width  = supported_modes[fse->index].width;
                      	fse->max_height = supported_modes[fse->index].height;
                      	fse->min_height = supported_modes[fse->index].height;
                      	return 0;
                      }
                      
                      

                      然后重新编译一下再测测。

                          @aike 我们对接rk平台的经验中,只有一个厂家的板子遇到了给你这个完全一样的问题,就是用上次帖子中的方法解决的。该问题原因是此板厂提供的linux内核,调用veyecam2m_enum_frame_sizes时没有正确的传入fse->code参数,导致参数验证失败。

                          如果你这个方法解决不了问题,建议打开驱动中的DEBUG_PRINTK宏定义,查找一下哪个函数返回报错了。
                          如果只是打开这个宏定义不够,需要你手动在这些函数返回错误的地方增加打印信息,进行查找报错处。
